The Glucose test strip is specific to testing glucose (detects 0 – 3000 mg/dL or 0-3%)and is intended for educational use only. The strip can be used to measure glucose levels in osmosis/diffusion experiments, urine analysis (educational only), and food science studies. NOTE: The Glucose test strip is not intended for medical diagnosis. Should you decide to test your urine & you get a positive result you should report it to your physician and test your blood sugar levels. In solutions containing oxidizers, a false positive may be observed. The glucose test strips use an enzyme that is specific for glucose. In order for the enzyme to work properly, the glucose needs to undergo mutational. In water samples, this process can take up to 3 hours.
